An archaeology museum in Philadelphia has made an extraordinary find — in its own storage rooms.

The Penn Museum, part of the University of Pennsylvania, announced Tuesday that it had 'rediscovered' a 6,500-year-old human skeleton believed to have been a well-muscled man of at least 50, who stood 5 feet, 9 inches tall.

The remains were originally excavated from southern Iraq around 1930.

Museum officials said the complete human skeleton had been stored in a coffin-like box in one of their rooms for the last 85 years.

What do we have here?: Scientists at the Penn Museum say they have uncovered a 6,500-year-old skeleton of a 50-ish man in a coffin-like box in a basement storage room for the last 85 years - with no catalog card or identifying information

Boo: The remains of this man, dating back to about 4400 BC and found in what is now southern Iraq in 1930, have been 'rediscovered'

Ancient: The skeleton has been nicknamed 'Noah' because records show the man survived an epic flood

Up-close: The remains were originally excavated from southern Iraq around 1930

Mint condition: The skeleton originally was discovered in 1929-30 by Sir Leonard Woolley's joint excavation team from the Penn Museum and the British Museum in London

All traces of its original identifying documentations have been lost, but the museum were not worried.

A records digitization project was recently undertaken, with University of Pennsylvania researchers, working with a team from the British Museum, determining the remains were first unearthed at the site of Ur, an ancient city near modern-day Nasiriyah, around 1929-1930.

The major archaeological project was lead by Sir Leonard Woolley.

They excavated nearly 50 feet to reach a site that became known as 'The Royal Cemetery'.

During the excavation, the team hit a layer of silt, which Woolley referred to as the 'flood layer', because it was ten-feet deep in some places but still technically up sea level.

He determined that the original site of Ur had been a small island in a surrounding marsh.

Then a great flood covered the land in the Ubaid-era.

Some 48 graves were dug up.

Transport: Workers carry the incredible find out of the digging site in 1929/1930

Leader: British archaeologist Charles Leonard Woolley (1880-1960) during his excavations at Ur in 1922-34

However the only skeleton in good enough condition to recover was the one now found at the Penn Museum.

The bones and surrounding soil was coated in wax and the entire skeleton was shipped to London, then on to Philadelphia.
